What Language Does Unreal Engine Use?

Published on November 20th, 2024

Have you ever wondered how stunning games are made? Well, the credit goes to Unreal Engine! It is at the core of developing most games that you love. In fact, 50% of the top games today use Unreal Engine. It is a powerful tool that enables developers to create immersive experiences that attract gamers. Developers utilize its powerful graphics and flexible programming options to develop versatile games. The platform allows developers to use different programming languages, each suited to specific project needs and offering unique benefits.

Because of all the advantages this platform offer, Unreal Engine is the top choice for both beginners and experienced in the game development community.

But how does Unreal Engine build such stunning games? What languages does Unreal Engine use? 

Let’s dive deep into it!

Primary Languages Used In Unreal Engine

So, what coding languages does Unreal Engine use? Well, the versatile gaming platform uses two primary languages – C++ for high-performance, and Blueprints for visual scripting. Each serves different purposes while offering flexibility to programmers and non-programmers.

Let us explore the programming languages in details:

C++ – Core Language Of UE

C++, as known, is a robust programming language that offers developers complete control over game mechanics and performance. It allows for deep customizations, which make it possible to handle complex tasks, such as real-time AI behavior, physics, and advanced rendering. C++ is also a performance-driven language, which is why it is the right choice for resource-heavy games.

In addition to C++, experienced game developers also use ‘Unreal C++’ – a variant of standard C++, specifically designed for game development. It comprises unique features that enhance the development experience. It comes with a reflection system that allows developers to use macros like UCLASS and UPROPERTY to manage game objects and properties. The engine’s built-in garbage collection, efficient memory management for UOBJECT instances.  

Further, Unreal C++ seamlessly integrates with Blueprint, allowing for a smooth combination of code and visual scripting. This combination enables developers to create immersive gameplay experiences while leveraging the power of C++.

Advantages of Unreal C++

• Optimized code execution that ensures smoother gameplay experience.
• Simplified memory management with reduced memory leaks.
• Large community for developers to access tutorials, plugins and other tools and resources.

Use Cases Of C++ In Game Development

Some of the examples of tasks handled in C++ are creating custom gameplay logic, controlling animations, and managing state of the game.

Blueprints – Visual Scripting For Non-Programmers

It is the visual scripting language of Unreal Engine that enables developers to create gameplay elements without writing any code. This tool is primarily useful for designers and artists who may not have a programming background. Blueprints allow them to simply drag-and-drop interface, enabling users to connect “nodes” that represent game functions. This makes it intuitive and easy to understand. Think of it like a node system, where you simply drag and connect different actions and events to build complex game behaviors without needing to code.

In addition, it is user-friendly and seamlessly integrates with C++.

Advantages of Blueprints

• Perfect for non-coders, as there’s no coding required.
• With rapid prototyping, you can quickly test and modify game ideas.
• Blueprints can work alongside C++, allowing developers to combine both systems.

Use Cases Of Blueprints In Game Development

Blueprints are often used for managing movements of characters, handling animations, and simple logic systems. Many game developers rely on Blueprints to build their entire game, while others use it for fast prototyping before converting parts into C++ for optimization.

Tips for Beginners and Experienced Developers

Here are some tips to start with game development using Unreal Engine:

• For beginners: Start with Blueprints to learn game mechanics without worrying about coding. As you get used to it, slowly move to C++ to improve your skills.
• For Experienced Developers: If you already know C++, get familiar with it well for advanced game features. Use Blueprints for rapid prototyping and testing ideas before implementing them in C++.

Choosing the right language in Unreal Engine depends on your project needs and expertise. However, you can embrace both C++ and Blueprints for the best development experience. Learn More: How to Make a Mobile Game App

Other Languages And Tools

While Unreal Engine at its core uses C++ and Blueprints for game development, there are other programming languages at play as well. These include Python and Material Editor.

Python

Python plays a crucial role, especially in automation and tool development. It is commonly used for scripting tasks, like automating repetitive actions in the editor or creating workflows for game development teams. Python allows developers to efficiently manage assets, create tools to enhance productivity, and perform batch processes.

Being a versatile programming language, Python can be especially useful for developers working on large-scale gaming projects where workflow automation is essential.

Unreal Engine started supporting Python scripting in version 4.19. It allowed developers to extend the editor’s capabilities without needing to dive into C++. This addition has made Unreal Engine even more flexible for diverse game development needs.

Material Editor 

Another tool within Unreal Engine is the Material Editor. It provides a visual scripting interface to create and manage shaders and materials. Instead of writing code, developers use node-based systems to connect various properties, defining how objects in a game look. This is extremely useful for developers and artists who are not comfortable with traditional programming.

The Material Editor also integrates well with other languages used in UE, such as C++ and Blueprints. For example, materials created with the editor can be dynamically adjusted through C++ or controlled by Blueprints during gameplay. This combination of visual and code-based tools makes Unreal Engine a powerful platform for both technical and non-technical users.

The Final Words 

So, to conclude, if you are thinking about “what language does Unreal Engine use?” the main answer is C++ and Blueprints. C++ is powerful for complex coding, giving developers control over performance and gameplay. On the other hand, Blueprints offer a visual way to script without needing deep coding knowledge, perfect for beginners or designers.

Both have their strengths and can be used together for a complete development experience. Exploring both will give you a better understanding of Unreal Engine and help you create more dynamic and engaging projects, regardless of your skill level.
